A pal of accused murderer Danny Pelosi took a car belonging to victim Ted Ammon to be washed hours after the millionaire’s brutal killing in his East Hampton mansion, prosecutors claim in court papers released yesterday.

The 1995 Buick station wagon that Chris Parrino had washed was found by authorities nearly six months later, on April 7, 2002, in “a driveway hidden from the road” at the East Hampton residence of a private eye retained by Pelosi’s lawyer, Edward Burke Jr., according to the documents.

Parrino, 36, has been charged with criminal facilitation and hindering prosecution in connection with Ammon’s murder, which occurred in October 2001.

Documents filed by prosecutors say that in January 2002, the Buick became a focus of the probe into the financier’s killing after cops began to suspect the car had been used in committing the crime.

Pelosi, a contractor who later married Ammon’s now-deceased widow, Generosa Ammon, was seen driving the car after the murder.

A tanned, rested-looking Pelosi – who is being held without bail – spent his 41st birthday yesterday in court as prospective jurors for his September trial filled out written questionnaires.

“No cake? No file?” quipped Pelosi to a reporter who noted the occasion.
